Board interlock configuration

The invention relates to a carton, in particular to a plurality of plates which can be fixed together in a lap joint configuration, ensuring a secure interlocking plate arrangement between the plates.

Wrap-around cartons and hand-packed top-loading cartons are well known and have long been used as effective, attractive and convenient secondary packaging for loading, storage and carrying. Ship multiple items. For example, such cartons can be used to group and carry multiple pieces of beverage containers, while also allowing such beverage containers to be exposed to the benefit of making and utilizing materials.

Wrap-around cartons and top-loading cartons are typically top grip, that is, they can be lifted from above using a handle assembly. The carton is often provided with an interlocking assembly because the underlying panels themselves must withstand the weight of the contents without reinforcement, so that the lapped panels are mechanically secured together. Therefore, the sheets of the carton must be securely and securely locked together so that when the carton is carried, the lap panels of the bottom panel are prevented from being separated, or the container pack being placed is improperly displaced.

Many of the interlocking configurations of the plates have been adopted in this technique, but most of them cannot completely limit the relative motion between the overlapping plates. In fact, some configurations can smoothly limit the movement of the lap panels away from each other along an imaginary plane defined by each other, but it is not possible to limit the movement of the slabs toward each other along the imaginary plane, or toward The movement away from each other in the direction orthogonal to the imaginary plane does not prevent lateral movement between the sheets.

However, the teachings of the present invention are also contemplated as being applicable to a variety of containers that may or may not be tapered and/or cylindrical in shape. Other items include metal or glass bottles, aluminum cans, bowling pins, and candles.

In order to teach the invention a variety of objects that are not limited thereto, a top loading carton pack embodiment for a multi-piece cylindrical can or bottle is illustrated to illustrate the sheet interlocking configuration L. The male locking tongue piece M and the female locking tongue piece F (shown in FIG. 2) of each plate interlocking configuration L (shown in FIG. 16) are defined on a blank piece 10, and the embryo is defined. The sheet can be made from a single piece of substrate that defines a plurality of hinged sheets therein. The inner surface of the green sheet 10 is shown in FIG.

Referring to FIG. 1, the blank 10 includes a series of sheets for defining the periphery of the carton 20, which includes a piece of end flaps 100, a first side panel 102 and a second side panel 104, and a first end panel. Sheet 106 and a second end plate 108. The upper edges of the peripheral panels collectively define a top edge 110 of the cargo compartment 20 and the lower edge collectively defines a bottom edge 112 of the cargo compartment 20.

The end flap 100 is hinged to the first side panel 102 along a fold line 114 that is hinged along the fold line 116 to the first end panel 106, the first end panel 106 being folded along The wire 118 is hinged to the second side panel 104, which in turn is hinged to the second end panel 108 along the fold line 120.

The carton 20 (shown in Figure 3) is provided with a composite handle panel H which is constructed from a plurality of other panels defined on the blank 10. Specifically, this The embryo sheet 10 includes a piece of intermediate plate piece 122 having a finger grip hole A, a piece of handle reinforcement plate piece 124 having a complementary finger grip hole A, and a piece of separator piece piece 126 which may also be provided with one or more finger grip holes A. The intermediate panel 122 is hinged to the handle reinforcement panel 124 along the fold line 128 and is hinged to the end panel 100 along the fold line 130. Additionally, the bottom edge of the intermediate panel 122 is hinged to the divider panel 126 along the fold line 132. In addition, one end flap 134 is hinged to the intermediate panel 122 along fold line 136 which is used to secure the intermediate panel 122 to the first end panel 106 when the carton 20 is assembled. Please explain later.

A plurality of divider strips are hinged to the intermediate panel 122 and the divider panel 126, and at least a portion is pressed therefrom. In particular, the first divider strip 138 and the second divider strip 140 are hinged to the intermediate panel 122 along fold lines 139, 141, respectively, each of the divider strips 138, 140 being spaced apart from one another and defining the intermediate panel 122 The fold lines 136, 130 of the side edges are equally spaced apart. The first divider strip 138 extends from the fold line 139 toward the second divider strip 140 and over the fold line 141 that connects the second divider strip 140 to the intermediate panel 122, thereby defining a tab T at its distal edge. . The second divider strip 140 extends from the fold line 141 toward the end flap 100 and extends over the fold line 130 to the end flap 100, thereby defining a tab T at its distal edge. Additionally, the web 10 may also be provided with a third strip 142 hinged to the divider panel 126 along the fold line 143, and a sheet hinged to the divider panel 126 along the fold line 145. Four dividers 144. The distal edge of the third divider 142 defines a tab T. The fourth divider strip 144 extends from the fold line 145 toward the third divider strip 142 and over the fold line 143 for attachment to the third divider strip 144 of the divider panel 126, thereby defining a tab T.

The web 10 includes a first bottom panel 146 and a second back panel 148 extending along fold lines 150 and 152, respectively, along which the fold lines are The bottom edge 112 of the carton 20 extends. The first backing sheet 146 and the second backing sheet 148 are configured to be secured together in an overlapping manner using a two piece interlocking configuration L constructed in accordance with the present invention. The female locking tongue F of the two-piece interlocking arrangement L is formed at the vicinity of the free edge 154 of the first bottom plate 146, and the complementary male locking tongue M is free from the second bottom plate 148. The proximal end of the rim 156 is formed. As will be readily appreciated by those skilled in the art, depending on the characteristics of the substrate used to form the carton 20, the characteristics of the item to be carried, and the structural design of the carton 20, the number of plate interlocking devices L can be Feel free to configure. The carton 20 shown in Figure 3 is designed to be transported in a 2x3 configuration, such as a can, such as a can, which can be attached to the floor panels 146, 148 alone or in combination with an adhesive. Together, the number and location of the plate interlocking arrangements L is therefore a design choice. As will be described later, the position of the plate interlocking configuration L can be matched with the position of the article and the strip of the carton 20 to prevent the plate interlocking configuration L from failing.

Referring now to Figure 2, the locking tongues F, M of the interlocking arrangement L of the plates are described in detail later. In particular, the male locking tab M defines a complementary opening on the second backing sheet 148 as it moves away from the imaginary plane of the second backing sheet 148. The male locking tab M is segmented to include a neck section 202, a shoulder section 204 and a tongue 206, however some sections are substantially adjacent to one another while others are folded along Wire hinged, or without a clear fold line connection, can only be bent between each other. In the illustrated embodiment, the neck section 202 is a semi-separated section adjoining the second floor panel 148 and is along a first arc cut line (or cut line) 210 by a substantially semicircle. The folded line 208 that is broken is hinged to the shoulder section 204, which is located in the middle of the fold line 208 and extends beyond the fold line to the shoulder section 204. In some embodiments of the invention, the neck section 202 can be omitted to allow the shoulder section 204 to be directly connected to the second floor panel 148, or The person uses a folding line provided between the two to connect. The shoulder section 204 is substantially wider than the neck section 202 and has a convex "flank" that defines its side edge profile. The tongue 206 defines the distal end of the male locking tab M, which is substantially wider than the shoulder section 204, but is about the same as the neck section 202. Therefore, the width W1 of the shoulder section 204 is greater than the width W2 of the neck section 202 and the width W3 of the tongue 206. The tongue 206 includes a substantial second semi-circular retention tab 212 formed along the distal edge 214 of the male locking tab M.

The female locking tab F defines a complementary opening in the first backing sheet 146. The female locking tab F is also segmented to include a neck section 220, a shoulder section 222 provided with a curved side edge, and a bracing section 224, however certain sections are substantially each other Adjacent, the other sections are hinged along the fold line or are not joined by well-defined and/or pre-scratched fold lines, which are only bendable relative to one another. In the illustrated embodiment, the neck section 220 is hinged to the first floor panel 146 along the fold line 226 and is hinged to the shoulder section 222 along the fold line 228. In addition, the fold line 228 is broken by a substantially semi-circular male retaining tab 230 that is positioned intermediate the fold line 228 and extends beyond the fold line to the shoulder section 222. The shoulder section 222 is contiguous with a bracing section 224 that defines a distal edge of the female locking tab F. The bracing section 224 is provided with a substantially semi-circular concave cutout 231 along the distal edge 236 of the female locking tab F, the concave cutout 231 defining a corresponding and substantially semi-circular convex on the first floor panel 146. The tongue 232 is shaped and held. In addition, the bracing section 224 and the shoulder section 222 are sometimes collectively referred to as a "head section."

The bracing section 224 defines the distal end of the female locking tab F, which is substantially narrower than the shoulder section 222, but is about the same as the neck section 220. Therefore, the width W4 of the shoulder section 222 is greater than the width W5 of the neck section 222 and the width W6 of the bracing section 224. The width of the neck section 222 is W5 It may be substantially equal to the width W6 of the bracing section 224. The bracing section 224 includes a second semi-circular cutout 231 formed along the distal end edge 236 of the female locking tab F.

Those skilled in the art will appreciate that the male retaining tabs 210, 212, 232 and the male cutout 231 are substantially semi-circular, but other shapes may perform the same function. Likewise, the raised side portions of the shoulder sections 204, 222 may also employ other useful contours consistent with the teachings of the present invention.

The latter is a method of bending the blank 10 for assembling the carton 20, but for ease of teaching, the bending operations shown and described may be exaggerated. First, the inner surface of the partitioning plate 126 is bent into a configuration in which it is in a facing relationship with the inner surface of the intermediate plate 122 and can be held by a suitable adhesive. Subsequently, the handle reinforcing plate 124 is bent along the folding line 128 such that the inner surface thereof is disposed to maintain a surface relationship with the outer surface of the partitioning plate 126 and the inner surface of the intermediate plate 122. . Both the intermediate panel 122 and the handle reinforcement panel 124 can be secured to the location by a suitable adhesive. However, in any event, the application of adhesive to the surfaces of the dividers 138, 140, 142, 144 should be avoided so that they can be deployed. The intermediate plate piece 122 is fixed to the handle reinforcing plate piece 124, and a portion of the partitioning plate piece 126 is disposed therebetween to form a composite handle piece piece H. The finger grip holes A on each of the sheets are set to be substantially aligned, whereby two openings for easily carrying the cartons 20 are formed on the handle sheets H. Anyone familiar with the art can easily know that the handle plate H can be provided with only one opening or more than two openings. Alternatively, other carrying devices may be utilized, including but not limited to external straps, T-bars, or fold-over sections.

Next, a method of assembling the carton 20 will be described. Once the handle plate is formed, the outer periphery P (shown in Fig. 16) of the carton 20 is constructed. Along the fold The stacking lines 114, 116, 118, 120 bend the green sheet 10 from the plane shown in FIG. 1 to cause the end flap 100, the first side panel 102, the first end panel 106, and the second side panel The first end plate 108 and the second end plate 108 are substantially at right angles to each other, and a portion of the inner surface of the second end plate 108 is in a facing relationship with the outer surface of the end piece 100. Thus, the first side panel 102, the first end panel 106, the second side panel 104, and the second end panel 108 define an outer periphery of the carton 20, a top edge 110 and a bottom edge 112, and the end panel 100 The outer surface P is fixed to the inner surface of the second end plate 108. The composite handle panel H was originally hinged to the end flap 100 and is now located within the outer periphery P of the carton 20. The free side edges of the composite handle panel H are secured to the abutment of the middle of the first end panel 106 by the end tabs 134. Therefore, the composite handle panel H divides the interior of the carton 20 into two, between the first end panel 106 and the second end panel 108, and the first side panel 102 and the second side panel. The sheets 104 are separated. Before or after the first backing sheet 146 is secured to the second backing sheet 148 using the sheet interlocking arrangement L of the present invention, the dividing strips 138, 140 are bent toward the second side panel 104, and the tongue T is utilized. The distal end is fixed, and the partition strips 142, 144 are bent toward the first side panel 102, and the distal end thereof is fixed by the tongue T. Prior to securing the first side panel 102, the second side panel 104, and the dividers 138, 140, 142, 144, the carton 20 may be first leveled for storage or, for example, transported to another location for finalization. Assemble and load items.

Finally, the first bottom panel 146 is secured to the second backsheet 148 by a lap joint configuration as shown in FIG. 16 to thereby form the bottom of the carton 20. Next, the first bottom plate 146 is bent upward along the folding line 150 to maintain a right angle with the first side plate 102, and the second bottom plate 148 is bent upward along the folding line 152 to form a second side plate 104. Keeping right angles, so that they are substantially in the same horizontal plane as shown in Figure 4, and their respective free edges 154, 156 are adjacent to each other.

As shown in the series of partial perspective and side views of Figures 4 through 15, the arrangement of the first backsheet 146 to the second backsheet 148 is secured by the panel interlocking arrangement L of the present invention. For ease of teaching, each view shows a plurality of different engagement stages for securing the components of one of the panel interlocking arrangements L of the bottom of the carton 20, and the first backsheet 146 and the second backsheet 148. The relative position of the components or their respective components may be exaggerated. As shown in Figures 4, 5, 8, 9, 11, and 13, respectively, various partial perspective views from a hypothetical site within the carton 20 are shown, as shown in Figure 15 from the carton. A partial perspective view of a hypothetical site outside the 20, and a partial side view as shown in Figs. 6, 7, 10, 12, and 14.

Referring now to FIG. 4, the male locking tab M and the female locking tab F are initially coplanar with the first bottom panel 146 and the second bottom panel 148. Next, as shown in FIG. 5, the female locking tongue F is bent outward along a folding line 226 located at the proximal end edge of the female locking tongue F, thereby revealing a female locking tongue M for receiving. The first opening O. The first opening O extends from the fold line 226 to an outer end 238. As shown in FIG. 6, the height of the first bottom plate 146 is slightly higher than that of the second bottom plate 148. As shown in FIGS. 7 and 8, the free edge 156 of the second bottom plate 148 is formed in the female lock. The base of the tongue F (and the vicinity of the proximal end edge) forms abutment with the neck section 220 and is substantially aligned with the fold line 226. In FIG. 8, the male locking tab M and a portion of the second bottom panel 148 (ie, the portion disposed between the male locking tab M and the free edge 156) are still coplanar and The outer surface of the first backing sheet 146 maintains a facing relationship so that it can be seen through the opening O, and the folding line 208 is at the vicinity of the free edge 154 of the first backing sheet 146, and the outer end of the first opening O 238 is substantially aligned. Referring to FIGS. 9 and 10, the shoulder section 204 of the male locking tab M is bent inward along the folding line 208. Folding causes the shoulder section 204 and the tongue 206 to pass through the first opening O. The outer end 238 of the first opening O is narrower than the shoulder section 204, thereby causing the shoulder section 204 to project a curved wing-like side edge against the edge of the first opening O. When the shoulder section 148 of the male locking tab M is bent out from the plane of the second bottom panel 148, a second opening is revealed on the second backing sheet 148 (shown in FIG. The first opening O is substantially longitudinally aligned with the first opening O, and the semi-circular male retaining tab 232 on the first backing sheet 146 is positioned thereon and substantially aligned with the curved cutting line 210. The convex portion defined by the semi-circular convex retaining tongue 232 and the curved cutting line 210 is engaged with the male locking tongue M to be defined when being bent upward through the opening O The hole 240.

Referring now to Figure 12, the female locking tab F is bent along the fold line 226 below the free edge 156 of the second backsheet 148. In this manner, the neck section 220 of the female locking tab F can be in a veneer relationship with the lower or outer surface of the visible "portion" of the second backing sheet 148, so that the second The portion of the bottom plate 148 is placed between the first opening O and the neck section 220 of the female locking tab F. Next, as shown in FIGS. 13 and 14, the head sections 222, 224 of the female locking tab F are bent upwardly about the outer end 214 of the second opening of the second bottom panel 148 along the fold line 228. . In this manner, the head sections 222, 224 of the female locking tab F are inserted and thus received within the first and second openings such that the male and female locking tabs M, F are each The distal edges 214, 236 are located above the upper or inner surface of the first backsheet 146. This situation is detailed in Figures 13 and 14, wherein the male locking tab M is in the bent position and the female locking tab F is in the holding position. When the male and female locking tongues M, F are respectively in the bending and holding position, that is, the two tongues are in a position of mutual support, thereby preventing each other from bending back to the original in the second The initial position in the plane of the first backplane sheets 148, 146. In phase In the position of mutual support, the head sections 222, 224 of the female locking tongue F can support the male locking tongue M, so that the male locking tongue M abuts against the female locking tongue F Distal edge 236. In addition, if it is in another optional mutual support position, the male locking tongue M is supported by the head sections 222, 224 of the female locking tongue F, so that the female locking tongue F The head sections 222, 224 abut against the distal edge 214 of the male locking tab M. However, in the embodiment shown in Figures 13 and 14, the male and female locking tabs M, F may alternatively be supported by another type of support, wherein the distal end edge 236 of the female locking tab F is concave. The slit 231 engages with a male retaining tab 212 projecting from the distal edge 214 of the male locking tongue M. As shown in Fig. 15, a view from a hypothetical base below the bottom side of the carton 20 shows the male locking tab M and the female locking tab F thus engaged. In this state, the plate interlocking configuration L is fully engaged.

It should be noted that the female locking tongue F is not necessarily bent to the 90 degree position as shown in FIGS. 9 and 10. Another alternative method is shown in Figure 17, wherein the female locking tab F is pushed out of the plane of the first backing sheet 146 to the extent that the second backing sheet 148 is free to be used. The rim 156 slides over the female locking tab F and below the free edge 154 of the first backing sheet 148, thereby aligning the male locking tab F with the opening O. Then, an action is performed, for example, a punching action is performed on the automatic packaging device to force both the female locking tongue F and the male locking tongue M to pass up through the opening O. Referring now specifically to Figures 19-21, the punching action illustrated is to apply a force to the underside of the female locking tab F (as indicated by the direction of the arrow) to drive it upward through the opening O, thus the yin The locking tongue F in turn hits the male locking tongue M, causing the female locking tongue F to yield to the female locking tongue F, and as a result, pushes up as shown in FIG. When the female locking tab F is fully extended, the concave cutout 231 of the distal edge 236 is generally upward as shown in FIG. 21 and along the distal edge of the male locking tab M. 214 engages the male retention tab 212.

Figures 22 through 31 are respectively partial perspective views of a series of steps taken by another available method. When the above-mentioned bending operation is performed on the carton 20, the initial treatment of the first bottom plate 146 and the second bottom plate 148 is likely to be as shown in FIG. 22, respectively, from the first side plate 102 and the second side plate. 104 extends downward (none of the side panels is not shown in Figs. 22 to 31). In Fig. 23, an automatic packaging device such as a punch or a folding wheel bends the female locking tab F from the plane of the first backing sheet 146 to define an opening O. Next, in Fig. 24, the first bottom sheet 146 is bent upward toward the inside of the carton 20 (not shown).
